Hi Sergey,

The problem is that the cursor is not necessarily anywhere near the item

I'm trying to delete. I have a pointer to the item, a pointer to its

parent RVData, and its item number within its parent RVData. However, I

don't know whether this particular item is inside a table cell or not.

As far as I understand it, rve.TopLevelEditor will return the editor

containing the caret.

A little background: I'm still working on footnotes, and making a lot of

progress. I've succeeded in writing all the insertion code (finding

which footnote number is being inserted, renumbering subsequent

footnotes, etc.), and I'm now working on deleting a footnote. The issue

is that in my app, the user will be able to read footnote contents in a

list, and may elect to delete a footnote without reference to where it

happens to be in the text. I have to then find the footnote number in

the text (which I can do), delete it (the difficult bit), and then

renumber any subsequent footnotes (no problem). By iterating through all

the items in the document recursively, I have a list of them in order,

and I've stored a pointer to the item (TRVCustomItemInfo), its item

number, and its parent TCustomRVData. I can do a lot with this, but I

don't seem to be able to delete the item safely.

Cheers,

Martin
